@dmckee I am not sure about QFile/QTextStream performance. Current code uses them, so I will give them a try. For the moment I would like to get rid of the central writer thread. Question is still open: Is it allowed to call QFile and QTextStream methods from multiple threads (with or without a mutex... (more) |

@ArtOfCode I guess the second notification was due to my successful retry. I deleted that one as well. However this means the failed tries didn't create any notifications. (more) |

First one was "Your solution is how I have solved it currently (well, a bit more complex but it boils down exactly to your idea). However moving the file work into a single writer thread does not scale." But as I said, other comments also didn't work. I tried many times. I just retried and now it wor... (more) |

| Question | — |
Editing tags failed? I edited the tags of my very first Codidact question: https://software.codidact.com/posts/281486 Someone proposed the "python" tag. Since I am working with C++, I removed the "multithreading" tag and added "C++". (I am not sure if that was a good idea. But that is not my problem.) Current state ... (more) |
